As shown in fig. 1 to 9, a plurality of electrically controlled telescopic legs 503 are fixedly arranged at the bottom of the housing 5.
When the belt conveyor is particularly used, a worker verifies and appropriately adjusts concentricity of the tail rotating shaft 2 of the belt conveyor and the outer circular arc rail 502. After ensuring concentricity of the belt conveyor tail shaft 2 and the outer circular arc rail 502, the industrial personal computer 501 commands the first electric control push rod 708, the second electric control push rod 709 and the scraping electric control push rod 802 to extend out by a proper distance (the sleeves 707 on the outer front shaft 701 and the outer rear shaft 702 are in contact with the conveyor belt 4, and the scraper 804 is in contact with the conveyor belt 4), and then the circulation motor 705 is operated. The scraper 804 and the scraper bar 807 clean the conveyor belt 4 and the skirt 402, respectively.
The specific verification and adjustment principle of concentricity of the belt conveyor tail rotating shaft 2 and the outer circular arc rail 502 is as follows: the worker pushes the detection box 601, so that the detection box 601, the lug plate 602 and the clamping rail member 603 slide along the outer circular arc rail 502. In this process, the round-head folding bar 604 contacts with the belt conveyor tail rotating shaft 2. When the belt conveyor tail rotating shaft 2 and the outer circular arc rail 502 have good concentricity, the indication of the pressure sensor 605 displayed on the industrial personal computer 501 should be kept constant. If there is a fluctuation in the indication of the pressure sensor 605 displayed by the industrial personal computer 501, it is indicated that the eyelet folding bar 604 is pushed and the detecting spring 606 is pressed and deformed. The front and back positions of the shell 5 and the extension length of the electric control telescopic supporting leg 503 need to be adjusted, so that the concentric relation between the tail rotating shaft 2 of the belt conveyor and the outer circular arc rail 502 is ensured. After concentricity adjustment is finished, because the detection box 601 and the lug plate 602 are in a detachable connection relationship, a worker can directly detach the detection box 601 and the inner round head folding rod 604, and interference between the subsequent round head folding rod 604 and the belt conveyor tail rotating shaft 2 is avoided.
The working principle of the avoidance unit 7 and the scraping unit 8 is as follows: the barrier rib 706 is attached to the underside of the separation barrier 401 and changes shape as the separation barrier 401 moves. When the separation shutter 401 is sufficiently close to the outer front shaft 701, the push switch 7011 on the outer front shaft 701 is triggered, and the first electric push rod 708, the second electric push rod 709, and the scraping electric push rod 802 are commanded to be pulled away by the industrial personal computer 501, and then extended to the original position again after a short standby time. Since the separator plates 401 on the conveyor belt 4 have periodicity, the outer front shaft 701 is about to collide with one separator plate 401, and the outer rear shaft 702 and the doctor 804 are about to collide with the separator plate 401 nearest to each other. So that when the push switch 7011 is triggered, the scraper 804 can be timely pulled away and avoid mechanical interference with the separation blade 401.
When the scraping electric control push rod 802 pushes the scraper 804 to be close to the conveyor belt 4, the lateral substrate 805 on the scraping electric control push rod 802 is also synchronously close to the conveyor belt 4, and two sides of the skirt 402 are inserted into the scraping rod 807, so that in the running process of the belt conveyor, the corrugated skirt 402 can push the scraping rod 807 and the sliding table 806 to slide forwards and backwards, and the continuous cleaning effect of the scraping rod 807 on the skirt 402 is ensured.
The operation of the circulation motor 705 can drive the baffle position indicating belt 706 to rotate continuously, so that the baffle position indicating belt 706 is prevented from being always partially contacted with the separation baffle 401, and the service life is greatly shortened.
The present invention is not limited to the above-mentioned embodiments, and any person skilled in the art, based on the technical solution of the present invention and the inventive concept thereof, can be replaced or changed within the scope of the present invention.
